Yes, because they're generated from the switch definitions in the code
of each program.

I'm not sure how.  For example, if a new switch is added, its mere
existence wouldn't be enough to let a *proc writer know whether or
how to use it.  It might help if a switch is removed, but that's
happened how many times in the history of MH and nmh?  And, the
*proc writer would likely have to do more than just notice that it
was removed.

But, it would add an interface that we would have to preserve.
I'm against doing that unless there's a benefit.  In this case, I
don't think there is one.  *proc's just aren't that well defined
(and I don't think this is a good place to start/continue), so the
writer sometimes has to know more than what's explicit in the
documentation already.
